ASK YOUR TEACHER

You may need to use the appropriate technology to answer this question.

Use the sample data below to test the hypotheses

H0: p1 = p2 = p3
Ha: not all population proportions are equal

where

pi

is the population proportion of Yes responses for population i.

Response Populations
1 2 3
Yes 145 145 106
No 95 145 114

Find the value of the test statistic. (Round your answer to three decimal places.)

Find the p-value. (Round your answer to four decimal places.)

p-value =

Using a 0.05 level of significance, state your conclusion.

Do not reject H0. We conclude that not all population proportions are equal.Do not reject H0. We cannot conclude that not all population proportions are equal.    Reject H0. We conclude that not all population proportions are equal.Reject H0. We cannot conclude that not all population proportions are equal.

You may need to use the appropriate technology to answer this question. Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, 30 employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by 10 workers. The number of units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting...
